The email was sent around 1 p.m. on Monday, June 17. At 4:20 a.m. the following morning, Hastings died when his Mercedes, traveling at high speeds, smashed into a tree and caught on fire. He was 33.

Hastings sent the email to staff at BuzzFeed, where he was employed, but also blind-copied a friend, Staff Sgt. Joseph Biggs, on the message. Biggs, who Hastings met in 2008 when he was embedded in his unit in Afghanistan, forwarded the email to KTLA, who posted it online on Saturday.

Here’s the email, with the recipients’ names redacted.

Subject: FBI Investigation, re: NSA

Hey (redacted names) — the Feds are interviewing my “close friends and associates.” Perhaps if the authorities arrive “BuzzFeed GQ,” er HQ, may be wise to immediately request legal counsel before any conversations or interviews about our news-gathering practices or related journalism issues.

In a rare move, the FBI issued a statement denying that Hastings was under investigation. The Los Angeles Police Department also said it had found no evidence of any foul play in his death.

Hastings, an accomplished war correspondent and sharp political reporter, was best known for writing a critical Rolling Stone profile of General Stanley McChrystal that led to his resignation.

It’s unclear what “big story” Hastings was working on prior to his death, but it might have to do with yet another military bigwig, this time retired general David Petraeus.

The LA Times reported that Hastings was researching a story about a privacy lawsuit brought by Jill Kelley, the Florida socialite who took center stage in the Petraeus cheating scandal, against the Department of Defense and the FBI. According to a person close to Kelley, the paper said, Hastings had plans to meet a representative of hers to discuss the case next week.
